Fantasy Tip: Celek was limited in practice throughout the week and was listed as questionable on the injury report. However, he won't have a great deal of fantasy value as long as TE Zach Ertz is healthy.

Philadelphia Eagles TE Brent Celek signed a three-year, $13 million extension Tuesday, Jan. 26, which includes $6 million guaranteed, according to sources.

Fantasy Tip: The Eagles are certainly committed to using their tight ends under new head coach Doug Pederson after Zach Ertz signed a hefty extension yesterday. It's clear Philly plans to use plenty of two-tight end sets in the years to come. Celek will have his fantasy value capped because of the presence of Ertz, but it doesn't mean he can't function as a valuable backup.

Fantasy Tip: After managing just seven catches for 71 yards through the first eight games, Celek has managed 11 catches for 213 yards in his last two. As long as Mark Sanchez is under center, Celek could have value a sleeper at the tight end spot.

Philadelphia Eagles head coach Chip Kelly has been using more two-tight ends sets with TEs Zach Ertz and Brent Celek to better suit the skill set of his tight ends and RB DeMarco Murray, which has come at the expense of the wide receivers. The Eagles has emphasized "12" personnel two-tight end sets for two straight weeks and have been rewarded with 202 combined receiving yards from Ertz and Celek.

Fantasy Tip: Ertz ($3,300, 6.6% of cap) has been the much more targeted and consistent tight end for Philly over Celek ($3,000, 6.0% of cap). Both won't be bad sleeper tight end picks at all on FantasyScore if this trend continues, and that's entirely possible with Mark Sanchez expected to start against the Tampa Bay Buccaneers this weekend.

Fantasy Tip: Celek ($2,200, 4.4% of cap) has been limited as of late by fellow TE Zach Ertz in the lineup, but Celek showed signs he won't go down without a fight. Keep an eye on if Mark Sanchez plays next week, as he could target different receivers. For now, note Celek will be spotty with his production.

Fantasy Tip: Celek has not been a big factor in the team's passing game over the past month but is facing a Washington Redskins defense that has allowed the most fantasy points to tight ends over the last four games. Celek only costs $3,000 on FantasyScore and could be a cheap option for owners looking to save some money at the position.
